Innovative heat exchanger design using extruded aluminium profiles for PCM-based TES systems

Abstract

We introduce an innovative heat exchanger design for phase change materials (PCM)-based thermal energy storage (TES) solutions. With buildings and industries facing peak energy demands and high costs, PCM-TES offers an efficient and sustainable solution. The novel heat exchanger design replaces conventional stainless-steel pillow-plates with extruded aluminium profiles, demonstrating enhanced affordability, competitiveness, and environmental sustainability. Achieving Technology Readiness Level 4 (TRL4), the proof-of-concept unit showcases a TES capacity of 160 Wh. This advancement addresses the challenge of low heat transfer rates, providing a cost-efficient solution for large-scale storage facilities. With a pending patent and plans for further development, this innovation promises to revolutionize PCM-TES technology, contributing to a greener and more energy-efficient future.
